Three new microcontrollers for automotive designs
Freescale Semiconductor has expanded its portfolio of Power
Architecture microcontrollers (MCUs) to address a broad range of
cost-sensitive automotive applications requiring 32-bit performance.
The company has introduced three new automotive MCU families optimized
for safety, chassis, instrument cluster, body electronics and gateway
designs.
Manufactured on 90-nanometer technology, the three Power Architecture
MCU families were developed collaboratively with STMicroelectronics as
part of a joint design program initiated in January 2006. Based on the
e200 Power Architecture core, the MCU products share a common hardware
and software ecosystem, which enables system designers to streamline
the development process by reusing code and development tools.
“Power Architecture technology is becoming the de facto 32-bit
standard for the global automotive market as the core architecture
continues to gain traction in application segments that require
exceptional performance and scalability,” said Paul Grimme,
senior vice president and general manager of Freescale's
Microcontroller Solutions Group. “The three advanced product
families are optimized for computationally demanding applications that
will help make the next generation of automobiles safer, more
affordable and driver-friendly.”
Chassis and safety control solutions
Freescale's MPC560xP MCU family is designed to help automotive
developers replace bulky hydraulic and mechanical components with
lightweight electrical systems that draw power only as needed.
Increased use of electrical systems in automotive designs helps reduce
vehicle weight and contributes to improved fuel efficiency, as well as
reduced greenhouse gas emissions. The MPC560xP family is designed to
benefit automotive chassis and safety applications, such as stability
control, electric power steering and braking, as well as hybrid
powertrain systems.
The MPC560xP devices feature fast analog-to-digital (ADC) controllers
and high-precision timers that work in concert for efficient
field-oriented control of electric motors. An on-chip cross triggering
unit enhances system efficiency and reduces system cost by managing
sample timing, which offloads the MCU core from frequent interrupts.
The high-resolution 120MHz PWM module supports key motor control
features, such as dead-time insertion, dead-time distortion correction
and advanced fault shut-down.
The automotive industry trend to replace mechanical systems with
electromechanical systems is driving the need for electronic components
to meet ever higher safety standards. The MPC560xP family helps
automotive designers implement systems that address key functional
safety requirements, such as IEC61508. Integrated features, such as an
on-chip fault collection unit, are designed to enhance the visibility
of MCU status. SRAM and flash memory include error correction coding
(ECC) capabilities. An on-chip temperature sensor and clock monitor
help detect system-level conditions. The MPC560xP family also supports
the FlexRay™ networking protocol, which is engineered to enable
robust, redundant in-vehicle communications at up to 10 times the speed
of other protocols.
Instrument cluster control solutions
The MPC560xS MCU family is designed to address the next wave of
automotive instrument cluster applications using color thin film
transistor (TFT) displays. Once limited to high-end vehicles, TFT
displays are growing more prevalent in low-end to mid-range vehicles.
The MPC560xS product family addresses the system requirements of
entry-level, yet sophisticated, instrument cluster applications with a
cost-effective, single-chip solution that directly drives the TFT
display. The MPC560xS devices not only are designed to support TFT
displays in automotive dashboards, they also can drive analog gauges
and liquid crystal displays (LCDs).
The MPC560xS MCUs feature a sophisticated, integrated display control
unit (DCU) designed to drive TFT LCD displays in up to wide quarter
video graphics array (WQVGA). Internal memory resources easily handle
complex graphics contents (pictures, icons, languages, fonts) on a
color TFT panel. Graphical content on screen sizes of up to half VGA
(HVGA) can be addressed by expanding the memory using a quad serial
peripheral interface (QuadSPI) for serial flash memory. The MPC560xS
family provides a scalable solution, with 1MB flash sizes sampling now,
as well as larger and smaller flash versions that are planned for the
future.
Body electronics and gateway solutions
Freescale's MPC560xB MCU family is designed to provide exceptional
price/performance for use in central body controllers, gateways,
comfort features (doors, seats, interior lighting), security/safety
features (passive entry systems, immobilizers, tire pressure monitoring
systems) and lighting control systems (headlights, brake lights, turn
lights).
The MPC560xB MCUs include on-chip modules for Controller Area Network
(CAN) and Local Interconnect Network (LIN™) communications, in
addition to other peripherals necessary to implement a wide range of
functionality in automotive body networks. Starting with a 512KB
version, the MPC560xB family will have a wide range of flash memory
options, enabling developers to migrate to higher performance
solutions. The MCUs include an instruction set enhancement allowing
variable length encoding (VLE) for code size reduction. Encoding of
mixed 16-bit and 32-bit instructions enables developers to achieve
significant code size reduction for body applications.
Comprehensive development support
Freescale's automotive MCUs built on Power Architecture technology are
supported by a comprehensive ecosystem of evaluation boards and
software tools, including compilers, debuggers and modeling tools.
Access to this mature ecosystem reduces application development
complexity and debugging/validation time during prototyping and
software integration phases. Freescale offers standardized AUTOSAR and
motor control libraries designed to help automotive designers reduce
development time and optimize application performance.
